FFTW is a free collection of fast C routines for computing the Discrete
|
||
|
|
Fourier Transform in one or more dimensions. It includes complex, real,
|
||
|
|
symmetric, and parallel transforms, and can handle arbitrary array sizes
|
||
|
|
efficiently. FFTW is typically faster than other publically-available FFT
|
||
|
|
implementations, and is even competitive with vendor-tuned libraries.
|
||
|
|
|
||
|
|
There are several machine-dependent optimizations that can be enabled in order
|
||
|
|
to generate SIMD code; take a look in fftw.SlackBuild to enable them.
